I think Joey was first and then Stacy. Then I watched Stacy more than Joey and still do, but like I said I used to find Stacy's vids more entertaining, but with the editing been watching Joey's version of collabs more.
BallisticSquid and Stampy seem to have nice videos, but since I don't play the xbox version and it seems vastly different from vanilla I enjoy, I don't tend to watch. Although Stampy also plays DI, though I wish he and others did more creative sandbox play and not just playsets.
